Fix npm deprecation warnings and update dependencies

- Update ESLint from 8.x to 9.x to resolve deprecation warnings
- Update glob from 7.x to 10.x for better performance and security
- Update js-yaml from 3.x to 4.x for latest security patches
- Update node-fetch from 2.x to 3.x with dynamic import support
- Replace gulp-clean with modern 'del' package to avoid rimraf issues
- Remove unused glob-all dependency
- Fix unused error variables in events.js for ESLint compliance
- Update fetch-events.cjs to work with node-fetch v3 ESM format

All builds and linting now pass without warnings
